to add a pinery to their existing ranges of glass structures, 

 that a house of this kind, 120 feet long, in four compartments, 

 three of 32 feet each for summer fruiters, succession plants, and 

 suckers, and one (nearest the heating apparatus) of 24 feet for 

 winter fruiters, would meet all ordinary requirements for Pines. 

 It is an easy matter to double, treble, or quadruple the number 

 of houses if necessary. The three first-mentioned divisions 

 should be provided with four rows of 4 -inch pipes, set at equal 

 distances along the bottom of the central bed for supplying 

 bottom-heat to the plants when plunged therein, and three rows of 

 piping in front and two at the back for top-heat ; adding two 

 extra pipes, one in the front and one at the back, for extra top- 

 heat in the house set apart for winter fruiters. The division set 

 apart for suckers should be the farthest from the heating 

 apparatus, and be 2 feet lower at the back and 1 in front than 

 the three preceding compartments. It should also have a space 

 ranging from 18 inches in front to 2 feet at the back between 

 the surface of the bed and the roof-glass, in order to bring the 

 suckers well up to the glass when plunged in the bed. There 

 should be a screw-down valve in the flow-pipes in each of the 

 four divisions of the house, and also in the flow-pipe at the point 

 where it enters the bed in the first division, to enable the 

 gardener to regulate the bottom-heat. 



There are various kinds of thoroughly reliable heating appara- 

 tus to choose from nowadays, from the plain saddle, gold medal, 

 Trentham, Cornish, Horizontal Monarch, Champion Horizontal 

 Tubular, up to the celebrated Patent Duplex Upright Tubular 

 Boiler, any one of which, of sufficient capacity for the piping 

 attached thereto, will give more or less satisfaction if properly set 

 and well stoked. 



There can be no question in the, minds of practical men as to 

 the advantages which modern pineries have over the old-fashioned 

 structures for growing and fruiting the plants in, although some 

 of these are still doing fairly good service in different parts of 

 the country. At the same time there is no doubt whatever but 

 that men of equal ability in the culture of Pines, but one having 

 old-fashioned pineries and the other houses such as I have 

 described, are unequally matched, and the man who has the 

 most approved appliances will produce the better Pines, simply 

 as the result of superior accommodation.
